RELATED CASES This application is a continuation-in-part of copending Ser. No. 571,697, filed Aug. 11, 1966, now abandoned.

DESCRIPTION OF THE INVENTION General I This invention relates to novel substituted triazones, particularly to tetrahydro-s-triazin-Z[1H]-ones, and to their use as hypoglycemic agents.

The compounds of this invention have the formula:

where R1 is wherein n is 0, 1, or 2; R can be the same as R or hydrogen.

3,484,439 Patented Dec. 16, 1969 ICC The terms cycloalkyl," cycloalkenyl, bicycloalkyl, bicycloalkenyl, tricycloalkyl, and tricycloalkenyl as used herein are intended to include the respective group optionally substituted on the ring or on the ring portion of the group with substituents which will not interfere with the desired hypoglycemic activity of the compounds of the invention. Illustrative of such optional substituents, but not necessarily all inclusive, are alkyl or alkoxy groups containing one or two carbon atoms.

In accordance with the present invention, I have discovered that compounds of the above class are effective as hypoglycemic agents. These compounds are orally active antidiabetic agents useful for lowering blood sugar content in warm-blooded animals as evidence by in vivo tests in rats and dogs. The hypoglycemic activity of these com-- pounds can be readily demonstrated by animal tests which are known to correlate with antidiabetic activity in man, such as those reviewed by Auguste Lobatieres in chapter 37 Hypoglycemic Agents, vol. II, Academic Press, London (1964).

The preferred compounds because of their outstanding hypoglycemic activity include where Z is methyl, ethyl, acetyl, chlorine or bromine; R and R are the same or different and are alkyl of 3-6 carbon atoms, cycloalkyl of 5-7 ring carbon atoms, bicycloalkyl or bicycloalkenyl of 7 or 8 ring carbon atoms, tricycloalkyl of 10 ring carbon atoms.

Methods of preparation where R; and R have the same meaning as defined above. The reaction may be accomplished in the absence of solvent or in the presence of an inert anhydrous solvent such as dioxane, toluene or acetone. The reaction occurs readily at temperatures between 10 and 100 C.

Certain of the compounds of this invention can also be made by a second process, which uses a 1-arylsulfonyl-3- alkylurea, formaldehyde and an acid catalyst. This reabove equation are different, the product triazinone will be present as a mixture of our compounds as follows:

The reaction of a substituted sulfonyl urea is effected If desired, these compounds can be separated by fractional in solution of a suitable anhydrous solvent at temperatures crystallization, chromatography, or other known methods of 2050 C. with either paraformaldehyde or s-trioxane which will be obvious to those skilled in the art. as the source of formaldehyde. Suitable solvents for the This reaction is performed in the same manner as that reaction are dioxane, dimethylformamide or dimethyldescribed in the second method given above, except that sulfoxide. An acid catalyst is required for the reaction. an amine salt of the 1-arylsulfonyl-3-alkylurea is used Sulfuric acid and p-toluenesulfonic acid, for example, are instead of the urea. suitable catalysts.

The solution is cooled to 15 C. and washed with 2 N hydrochloric acid and saturated aqueous sodium bicarbonate. After drying with anhydrous magnesium sulfate, the solvents are removed by stripping under reduced pressure. The residue is recrystallized to give essentially pure 1-(p-toluenesulfonyl)-3,5- di- (n-butyl tetrahydro-s-triazine-2[ 1H] -one.

All of the compounds named in Examples 290 can be also prepared according to this procedure by substituting the appropriate urea for 1-(p-toluenesulfonyl)-3- (n-butyl)urea employed above. In addition, the following tetrahydro-s-triazin-2[1H]-ones of this invention can be prepared according to this procedure by substituting the following urea reagents for 1-(p-toluenesulfonyl-3-(nbutyl)-urea employed above.

174 parts by weight of benzene and 7.3 parts by weight of n-butylamine are stirred at room temperature. Next, 6.6 parts by weight of paraformaldehyde and 0.3 part by weight of p-toluenesulfonic acid monohydrate are added and the mixture is refluxed under a Dean-Stark trap until water is no longer evolved. The solvents are removed by stripping under reduced pressure and the residue is recrystallized to give essentially pure 1-(p-toluenesulfonyl)-3,5- din-butyl -tetrahydr0-s-triazin-s[ 1H] -one.

Next, 3.3 parts by weight of paraformaldehyde and 0.3 part by weight of p-toluenesulfonic acid are added and the mixture is treated as described in Example 98. The crude syrupy residue contains the following four compounds in approximately equal amounts; 1-(p-toluenesulfonyl)-3,5- diisopropyltetrahydro-s-triazin 2[1H]-one, 1 (p-toluenesulfonyl) 3,5 dicyclohexyltetrahydro-s-triaziri 2- [1H]-one, 1 (p-toluenesulfonyl) 3 isopropyl 5 cyclohexyltetrahydro-s-triazin 2[1H] one and l-(p-toluenesulfonyl) 3 cyclohexyl 5 isopropyltetrahydro s triazin-2[1H]-one. These compounds can be obtained separately by either fractional crystallization or by chromatography of the crude mixture.

The following tetrahydro-s-triazin-2[1H]-ones of this invention can be made similarly by substituting the following sulfonylurea reagents and amine reagents for 1- more other metabolically, therapeutically or nutritionally beneficial ingredients.

These compositions will ordinarily contain from about 10 milligrams to about 500 milligrams of a compound of the invention. A preferred composition will contain from about milligrams to about 500 milligrams of such compound. The active compound will normally constitute from about 1% to 95% by weight of the total composition. Ordinarily, since it will be desired to administer the active compound according to this invention in fairly concentrated form, i.e. with only so much pharmaceutical carrier as is necessary or convenient to assist in administration, the active compound will constitute under most circumstances a fairly high proportion of the total composition.
